x reaction at joint 1 (M sub 1x,) for GTSTRUDL result should be "-227.413
k-in" instead of "227.413 k-in".

DESCRIPTION:

Linear varying LINE LOADS created in GTModeler for elements which have
midside nodes on the loaded edge (IPQQ, IPQLQ4, IPQLQ1, IPQLQ2, IPQLQ2B,
IPQLQ3) are translated into GTSTRUDL incorrectly and also generated
incorrectly if the GENERATE INPUT file menu is picked.  The incorrectly
translated linear varying loads may be verified using the LIST SUM
REACTIONS command after a STIFFNESS ANALYSIS or by returning to GTModeler
and using the DISPLAY LOAD menu.  Note that the loads will appear to have
been generated correctly if they are displayed using DISPLAY LOAD before
returning to Command Mode or generating an input file.

Workaround:

Do not use GTMODELER to create linear varying LINE LOADS for elements
which contain midside nodes.  Return to command mode and using the
ELEMENT LOAD command to specify EDGE FORCES.

DESCRIPTION:

INERTIA LOADS (self-weight) created in GTModeler for the TRANS3D
TRIDIMENSIONAL element are incorrect.  The error may be verified using
the DISPLAY LOAD menu or the CHECK MODEL menu using the CHK LD SUM menu
pick.  The LIST SUM REACTIONS command may also be used after a STIFFNESS
ANALYSIS to verify that the reactions are incorrect.

Workaround:

Do not use GTMODELER to create INERTIA LOADS if the model contains
TRANS3D elements.  Return to command mode and using the ELEMENT LOAD
command to specify BODY FORCES for all the elements in the model.

Applicable Section of the Documentation:

GTMODELER - Volume 6 of the GTSTRUDL Users Manual
